Summary on Grant Application Form |
|
This project will study the dynamics through which a vortex ring impinging on a surface may lead to the resuspension of material from a layer of particles initially on the surface. This resuspension mechanism may be considered as one element of the process by which zero-mean flow turbulence is able to suspend particles.In many situations, the ability for a flow to resuspend particles depends also on the bed-form. Basic aspects of this will be investigated by considering the resuspension due to a vortex ring from a variety of different bed profiles.Measurements of th equantity and distribution of material resuspended will be obtained using the 'Depositometer', a novel instrument (recently developed by the PI) for measuring the thickness of a layer of sediment. The electronics and data reduction techniques used in conjunction wit the Depositiometer will be enhanced as part of this project, thus allowing improved spatial and temporal respolutions to be achieved.
